Thomas M. Davidson, 25, entered a not guilty plea to seven charges, including four counts of murder, in White County Circuit Court Monday morning.

Davidson's attorney, Jerry Crisel of Albion, entered the not guilty pleas on his client's behalf before Judge David K. Frankland.

The charges stem from the late-August shooting death of Sandra K. Burkhardt, who was allegedly brought to an a rural area one mile west of Crossville from her home in Gibson County, Ind., and shot to death by Davidson in a cornfield.

The judge formally advised Davidson of the seven charges during Monday's arraignment and the possible penalties if convicted. Each of the four murder charges can carry a penalty of 20 to 60 years in prison and include penalty enhancement of an additional 25 years because a firearm was used in the commission of the alleged offenses.

The other charges included aggravated battery with a firearm, aggravated vehicular hijacking and aggravated discharge of a firearm.

If convicted on the offenses, each sentence must run consecutively and could result in a natural life in prison sentence without the possibility of parole.

White County State's Attorney Denton Aud and Crisel agreed on a jury trial date of 9 a.m. Dec. 10 with final pre-trial set for Nov. 27. Davidson is due back in court at 9:30 a.m. Oct. 21 for a pre-trial hearing.
